Abstract
The utility model discloses a detonating mechanism used in deep hole blasting. The detonating mechanism comprises two detonator leg wires, wherein one ends of the two detonator leg wires are twisted and inserted into a plastic blasting guide pipe, the other ends of the two detonator leg wires are respectively connected to a blasting bus. The detonating mechanism is simple in structure, an electric spark generated by using the momentary discharge after the charging of an exploder detonates explosives on the inner wall of the plastic blasting guide pipe, so as to detonate the whole detonating network, the influence of external current is avoided, when the blasting bus is connected, the other detonator leg wire can be directly connected even the other end of one detonator leg wire in the two detonator leg wires is not connected, consequently, the purpose of safe detonation is achieved.
Description
Technical field
The utility model relates to the engineering explosion technical field, specifically a kind of ignition mechanism be applied in deep hole blasting.
Background technology
In engineering explosion, industrial detonator commonly used has blasting cap, electric cap and on-electric detonator etc.Because use limitation and the security reliability of blasting cap are poor, the use that has been eliminated at present, electric cap and on-electric detonator have been widely used in the engineering explosion operation.
Electric cap adopts the nichrome filament to do the bridge wire material.Iron payment to a porter electric cap impedance is not more than 6.3 Ω, and the bound difference is not more than 2.0 Ω, and bridge wire resistance bound difference is not more than 0.8 Ω.Copper payment to a porter electric cap impedance is not more than 4.0 Ω, and the bound difference is not more than 1.0 Ω.The maximum current that also can not explode by constant direct current 5min is called the safe current of detonator, and the safe current of existing national Specification electric cap is 0.18A." shotfiring safety rules " regulation, same blasting network, should use Tong Chang, with batch, the electric cap of same model.Because the bridge silk material that different manufacturers and different lot number are used and bridge filament diameter may be different, if in same blasting network, pass to identical electric current, may occur a kind of bridge silk to fuse and another kind of bridge silk not yet reaches the phenomenon of firing temperature, the cartridge bag that result causes miss-fires, produce blown-out shot, bring huge potential safety hazard.
Because the electric initiating networking is vulnerable to the impact of extraneous electricity, mainly comprise: the impact of the extraneous electricities such as thunder and lightning, stray electrical current, induced-current, static, radio frequency electrical (electric wave of the emission such as broadcast, TV, radio station), chemistry electricity, cause that electric cap is early quick-fried, cause security incident.Impact for fear of above extraneous electricity on bursting work, through technical research and test, what my mine adopted is non-electric Nonel detonator, non-electric shock conducting tube detonator is not subject to the impact of above extraneous electricity.In whole powder charge process, use non-electric shock conducting tube detonator to make igniting primer, do not relate to electric cap, after, networking complete until powder charge end, the filling of big gun hole connects and finish, the non-electric shock conducting tube detonator traction, to spacious place, is adopted to 1 generating cap sensitive.Yet this 1 generating detonator, also easily because of the impact of extraneous electricity, cause that morning is quick-fried, causes security incident.
The utility model content
The purpose of this utility model is to provide a kind of ignition mechanism be applied in deep hole blasting, is not subject to the impact of extraneous electricity, to reach the purpose of safe detonation.
The technical solution of the utility model is as follows:
A kind of ignition mechanism be applied in deep hole blasting, include two detonator payment to a porter, it is characterized in that: an end of described two detonator payment to a porter is twisted joint into twisted shape and is interted in plastic detonating tube, the other end of two detonator payment to a porter respectively with blow out bus and be connected.
The described ignition mechanism be applied in deep hole blasting, is characterized in that: in described plastic detonating tube, be provided with explosive.
The described ignition mechanism be applied in deep hole blasting is characterized in that: the described bus of blowing out is connected with initiator.
The beneficial effects of the utility model:
The utility model is simple in structure, sparking after utilizing initiator to charge, produce electric spark, ignite the explosive on the plastic detonating tube inwall, and then ignite whole blasting network, be not subject to the impact of extraneous electricity, connect while blowing out bus, even in two detonator payment to a porter, the other end of a detonator payment to a porter does not connect above, another root detonator payment to a porter also can directly connect, and has reached the purpose of safe detonation.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, a kind of ignition mechanism be applied in deep hole blasting, an end that includes 1,2, two detonator payment to a porter 1,2 of two detonator payment to a porter is twisted joint into twisted shape 3 and interts in plastic detonating tube, the other end of two detonator payment to a porter respectively with blow out bus and be connected.
In the utility model, be provided with explosive in plastic detonating tube; The bus of blowing out is connected with initiator.
Claims (3)
1. the ignition mechanism be applied in deep hole blasting, include two detonator payment to a porter, it is characterized in that: an end of described two detonator payment to a porter is twisted joint into twisted shape and is interted in plastic detonating tube, the other end of two detonator payment to a porter respectively with blow out bus and be connected.
2. the ignition mechanism be applied in deep hole blasting according to claim 1, is characterized in that: in described plastic detonating tube, be provided with explosive.
